BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle device provided on a door of furniture, a fitting or the like, and more particularly, to a door which can be smoothly operated by an external operation on the handle without being restricted by a mounting position of the handle. A handle device.

[0002]

2. Description of the Related Art There are various types of handle devices provided on doors of furniture, fittings and the like. When a door in a closed state is locked, a handle such as a handle is operated.
In some cases, the door can be opened by releasing the lock. FIG. 8 is an external view of a conventional handle device 100,
FIG. 2A is a front view showing a state in which the door 101 is attached to the back surface, and FIG. 2B is a plan view of FIG. As shown in FIG.
The main unit (first unit) 102 and the guide unit (second unit) 103 constituting the unit 00 are attached to the door 101 in an independent state, and such units 102 and 103 are connected to the units 102 and 10 respectively.
3 is connected to the knob 104 via operation shafts 105 and 106 extending from the handle 3, respectively. Then, by pulling the handle 104 in the direction of arrow P in FIG. 2B against springs (not shown) provided on the operation shafts 105 and 106, the lock is released and the door 101 is released. Can be opened.

As a conventional method for locking the closed state of the door 101, a so-called cam method is employed. FIG. 9 shows a state where the door 101 is locked.
0 indicates a state when the lock is released. In the main body unit 102 shown in FIG. 9, a cam body 108 having a support shaft 108a supported by a bearing (not shown) of a housing 107 is provided, and a projection 108b provided at one end of the cam body 108 is used as an operation shaft. The other end of the cam body 108 is engaged with a concave portion (not shown) of the cam operating body 109 attached to the
a, and at the lower end of the slider 110, an engaging projection 110b is provided so as to project therefrom.
Is a locking projection 1 fixed to a main body 111 such as furniture or fittings.
11a. In this state, the door 101 in the closed state is locked. When the lock is released and the door 101 is opened, when the handle 104 is pulled in the direction of arrow Q in FIG. 10, the cam operating body 109 also responds in this direction.
The protrusion 108b engaged with the concave portion 9 also moves in the arrow Q direction. Along with this movement, the cam body 108
, So that the other end of the cam body 108 slides along the upper end inner wall 110 a of the slider 110. Then, since the slider 110 moves in the direction of the arrow R in the figure, the engagement between the engaging projection 110b and the locking projection 111a is released, that is, the lock is released and the door 1 is released.
01 can be open.

[0004]

However, in such a conventional apparatus, the main unit and the guide unit are independently attached to the door, and both are connected via the knob. There is a bias in the operating force applied to the handle, such as by pulling at a position biased toward the main unit with respect to the handle, or by pulling at a position biased toward the guide unit.
When the lock is formed or released, malfunction may occur. In particular, when a long handle must be used, the separation between the main unit and the guide unit has to be increased, and the frequency of the above-mentioned malfunctions is even greater. Therefore, in the conventional device, the mounting position of the main unit and the guide unit is limited by the length of the handle (generally, the length of the handle is within 80 mm). In the case where both units are integrated via a handle, as shown in FIG.
Must be engaged with the locking projections 111a of the main body 111 such as furniture and fittings, and restrictions are imposed on the direction in which the handle is attached, that is, whether the handle is used vertically or horizontally. Was. Further, in the conventional device, a cam system is adopted for forming and releasing the lock, and the contact friction resistance generated between the members when transmitting the motion in the cam system is larger than that of, for example, the gear contact. In some cases, the operation of forming and releasing the lock is not smooth.

An object of the present invention is to provide a door handle device capable of forming and releasing a lock by a smooth operation without being restricted by a mounting position of a handle such as a handle. Another object of the present invention is to provide a door handle device which is not restricted by the direction in which the handle is attached, in addition to the above objects.

[0006]

In order to solve the above-mentioned problems, a door handle device of the present invention operates a handle such as a handle provided on furniture or a fitting to lock a door in a closed state.

Form. However, according to the sliding movement of the lever 31, the cam body 3
The rotational movement imparted by the shaft 2 to the shaft 4 is also transmitted to the body knit 2. Therefore, also in the main body unit 2, the rotational motion of the cam body 32 is added to the rotational motion of the first gear 12 via the shaft 4. That is, the sliding movement of the lever 11 is converted into a rotating movement, and the rotating movement transmitted from the shaft 4 is added to this rotating movement, so that the sliding movement of the lever 11 by the above operation is assisted from the guide unit 3 side. Form. In this way, at the same time as the power is transmitted from the main unit 2 to the guide unit 3 side, the power is transmitted from the guide unit 3 side to the main unit 2.
Since the power is transmitted to the side, the lock can be released by a smooth operation.

When the lock is formed, when the pulling operation of the handle 8 is released, the lever 11 is released.
Is returned to the original position by the urging force of the spring 19, and the engagement between the engagement projection 11c and the engagement projection 12a is released. And the engaging projection 13a projects from the opening 10c of the case 10. When the door 5 is closed with the engaging projection 13a protruding, the engaging projection 13
a comes into contact with the inclined surface of the locking projection 9a, and a force acts on the engaging projection 13a to retreat the engaging projection 13a into the case 10, whereby the engaging projection 13a is brought into contact with the locking projection. 9a, the engaging projection 13a and the locking projection 9a
Thus, a lock is formed. On the other hand, it goes without saying that the lever 31 has returned to the original position by the urging force of the spring 35.

Next, the second gear 1 in the main unit 2
The case where the shaft 4 is fitted into the fitting hole 14b of the fourth (second use mode) will be described. In this case, the shaft 4 is disposed in the fitting port 14b symmetrical with respect to the fitting port 12b and the lever 11. First, when the door 5 is unlocked and the door 5 is opened, when the handle 8 is pulled in the same manner, in the main unit 2, the lever 11 slides against the spring 19, and the second gear 14
The sliding of the engaging gear 11 causes the engaging projection 11d to move to the second gear 14
In order to push the engaging projection 14a, the rotary movement is performed by a predetermined angle. This rotational motion is transmitted to the idler A gear 15 meshing with the second gear 14, and further to the idler A gear 15
Is transmitted to the second rack gear portion 13c that meshes with
The latch 13 slides against the spring 21, and the engaging projection 13 a retreats into the case 10.
The lock formed by 3a and the locking projection 9a is released. On the other hand, in the guide unit 3, the same operation as in the first usage mode is performed, and at the time of power transmission, power is transmitted from the body nit 2 to the guide unit 3 at the same time as power is transmitted. Power is transmitted to the main unit 2 side, so that smooth unlocking can be performed. Also, the lock can be formed according to the case of the first usage mode.

Further, the fitting opening 16a of the idler B gear 16
The case in which the shaft 4 is fitted to the (third usage mode) will be described. In this case, the shaft 4 is

Also, when forming a lock,
It can be carried out according to the first and second use modes.

In these first to third modes of use, the shaft 4
Although the positions where are fitted are different from each other, the rotational direction of the shaft 4 is the same, so any one of the fitting ports may be appropriately used. Since the arrangement position of the engaging projections to be engaged does not need to be changed whether the handle is used vertically or horizontally, there is no restriction on the mounting direction of the handle 8 depending on the arrangement position. .

By the way, the device 1 is composed of a main unit 2
7 is transmitted to the guide unit 3 via the shaft 4 and at the same time, the power of the guide unit 3 is transmitted to the main unit 2 via the shaft 4. It can also be used.
In FIG. 7, the same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In the device 40 according to this usage mode, instead of attaching the handle 8, a knob 41 is attached to the operation shaft 7 of the guide unit 3, and a blind lid 42 is attached to the operation shaft 6 of the main unit 2.
The shaft 4 fitted in the fitting opening 32 b of the cam body 32 is fitted in the fitting opening 12 b of the first gear 12. In the present device 40, when unlocking and opening the door 5, when the knob 41 is pulled, the lever 31 slides against the spring 35, and the cam 32
In accordance with the sliding of the first unit 1, the engagement protrusion 31 c rotates to push the engagement protrusion 32 a of the cam body 32, and the power based on the rotation is transmitted via the shaft 4 to the main unit 2.
Is transmitted to In the main body unit 2, the first gear 12 rotates by the rotational force transmitted from the shaft 4.
Then, the first rack gear portion 13 meshed with the first gear 12
b, the latch 13 slides against the spring 21 and the engaging projection 13a retreats into the case 10, so that
The lock formed by the engaging projection 13a and the locking projection 9a is released. In the case where the lock is formed, when the pulling operation of the knob 41 is released, when the lever 31 returns to the original position by the urging force of the spring 35, the engaging protrusion 31c is engaged with the engaging protrusion 31c. Since the engagement with the portion 32a is released, the power is not transmitted to the first gear 12, so that the latch 13 meshing with the first gear 12 returns to the original position by the urging force of the spring 21, and The collision body 13a protrudes from the opening 10c of the case 10. When the door 5 is closed with the engaging projection 13a protruding, the inclined surface of the engaging projection 13a is locked by the locking projection 9a.
Of the engaging projection 13a, and a force is applied to the engaging projection 13a to retreat the interior of the case 10, whereby the engaging projection 13a rides over the locking projection 9a. A lock is formed by the projection 13a and the locking projection 9a. Needless to say, the lever 11 of the main unit 2 is unnecessary as long as it is used in such a usage mode. Such a use mode is a case where the knob 41 is used in place of the handle 8, and in particular, the arrangement position of the engagement projection 13 a and the locking projection 9 a is limited to a required position. This is effective in cases such as

Instead of fitting the shaft 4 into the fitting opening 32b of the cam body 32, the shaft 4 is
It is needless to say that the fitting mode may be a fitting mode in which the fitting port 14b of the gear 14 is fitted, or a fitting mode in which the fitting mode is fitted to the fitting port 16a of the idler B gear. It is even more effective when

The device 1 may be constituted only by the main unit 2. A knob is attached to the operation shaft 6, and the above-mentioned device is operated in accordance with the operation of pulling the knob and the operation of releasing the knob. It goes without saying that the lock may be released or formed.
